As a dry run I have been making a Rhino 3D model to figure out Galactica’s massing. It is a tough ship to figure out. This model is just a start and only to get the shapes figured out;

excelent work Cobywan , been itching to a Galatica cg model …
Someone years ago actually made a Galtica model kit many years ago, from the original series. My cousins and I found some that someone had thrown away. Wish that it had made it through the years of travell.
It was probably thrown away because of it’s extreme inaccuracies. It should have been anyway. 
Actually for it’s time and the series that was on at the time it was dead on.
Or, more precisely, at the time the kit was manufactured people didn’t care about accurace. “Good enough!” It was just as wrong from the studio miniature in 1978 as it is in 2005. 
I have some progress pics posted in this thread;

COOOOOL! [8D]
How big do you plan on building her? At what scale?
And - more importantly! - are you going to kit her? [:p] [:p] [:p]
